Sistem Teknik designs and produces ageing ovens for aluminium profiles. We offer double-length (max. 16 m) aging ovens with up to 24 baskets as well as single-length (max. 8 m) aging ovens with 12 baskets. By integrating smart loading cars into the system, we assure that production processes after extrusion are completely automated.
Ageing ovens are heated through electricity or natural gas (indirectly) up to 185 °C in less than 1 hour while the entire heat treatment process lasts for 6 hours, allowing the application to take place 4 times a day.
Temperature homogeneity inside the ovens is maximised with the use of the reversible end flow system (changeable air flow direction), ensuring excellent hardness over the whole length of the profiles.
The recirculation fan in the system directs the hot air generated in the thermoblocks into the oven by moving horizontally through the reversible end flow system. Depending on the desired time intervals during heating, ageing ovens can reach material temperature homogeneity in the range of ± 3 °C.
While two transfer cars located at the entrance and exit zones carry out the loading and unloading procedures, chain or roller conveyor systems can also be preferred.
